OBADIAH SEELY, OF SYRAOUSE, NEW YORK, ASSIGNOR TO E. C. STEARNS & CO.,OF SAME PLACE.

SAW-VISE.

SPECIFICATION forming part of Letters Patent No. 339,020, dated March30. 1986- Application filed January 27, 1886. Serial No. 189,890.

To all whom it may concern:

Be it known that I, @naman SEELY, of the city of Syracuse, in the countyof Onondaga and State of N ew York7 have invented a new and usefulImprovement in Saw-Vises, of

which the following is a specification.

This invention relates to an improvement in that class of vises whichare employed for holding saws during the operation of sharpenio ing thesame, and has for its object to provide suitable means for adjusting thevise to the most desirable position for light and to prevent vibrationsof t-he saw under the action of the iile, thereby avoiding` noise,lessening the lai5 bor of sharpening the saw, and reducing the wear ofthe files.

My invention consists to that end of the improvements which will behereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure lis afront elevation of a saw-viseprovided with my improvements. Fig. 2 is a sectional elevation at rightangles t0 Fig. l. Figs. 3 and 4 are horizontal sections in lines :t a:Vand y y, 2 5 Fig. 2, respectively. Fig. 5 is a front elevation of thelower part of the vise,showing the camlever released. Fig. 6. is a sideelevation of the washer of the adjusting device.

Like letters of reference refer to like parts 3o in the several iigures.

A represents the supportingclamp of the vise, which is fastened toaworkbench or other stationary support,A,by a clampingscrew, a.

B represents the stationary jaw of the vise 3 5 provided with adownwardly-extending arm, b, which is attached to the clamp A by aball-and-socket joint. The arm bis bifurcated at its lower end andterminates in two dependinglugs,b.

4o c c represent two arms,which rise from the lower bifurcated end ofthe arm b, and which are arranged at a short distance in front of thearm Z), to form a space for the reception of a saw between the arms cand the arm b. The

upper ends of the arms c are arranged at a suitable distance below thestationary jaw B, and receive a horizontal pivot-bolt, d, to which themovable jaw D is pivoted.

rIhe ball-and-socket joint by which the (No model.)

stationary jaw of the vise is attached to the 5o clamp A is constructedin the following manner:

e represents an opening formed in the arm b, and Eis ascrew-bolt passingthrough the opening e. llhe bolt E is provided with a rounded head, e',which is seated in the openinge, on one side of the arm b, so that thebolt can assume positions at various angles in the Opening e.

F represents a spherical washer arranged on the opposite side of the armb, and pr0- vided with a lip, j', which enters a recess or notch, f', inthe arm b, so that the washer moves with the arm of the vise and forms aknuckle for adjusting the vise on the clamp. 6 5

G represents a spherical socket formed on the upper end of the clamp A,and receiving the spherical washer or knuckle F. The screwbolt E passesthrough an opening in the clamp, which opening is somewhat larger thanthe diameter of the screwbolt, so that the latter has a certain play insaid opening.

His a screw-nut applied to the bolt E, on the rear side of the socket G,and provided with a handle or thumbpiece, so that the nut can be readilytightened and released.

Upon releasing the nut H the vise can be adj usted on the clamp A, sothat the jaws are either horizontal or inclined in one or the otherdirection, as may be necessary, in order to obtain the most desirableposition for light or convenience in filing.

The movable jaw D is provided with two downwardlyextending arms,l,whichare pivoted to the bolt d, between the arms c ofthe 85 stationary jaw,which latter are preferably connected below the pivot d and above theirlower ends by a cross-piece, i.

J represents a cam, which is pivoted to the lugs b,and which bearsagainst the lower ends ofthe arms I, for closing the movable jaw D. Thecam J is provided with a lever or handle, J for operating it, whichlever is curved upwardly, as represented in Figs. l and 2, so as to beout or' the way when the movable jaw is closed.

K represents an auxiliary movable jaw, which is arranged at a shortdistance below the jaw D, and provided with a'downwardlyf extending arm,k, lwhich'is pivoted to the b/lt d, between the arms I of the jaw D.-The lower end of the arm k rests against an eccentric projection orraised cam, Z, formed on the cam J, so that by turning the cam J bothjaws Dand K are closed successively.YV f

M represents a spring, which is secu red to the arm k of the auxiliaryjaw by a rivet, m, and which bears with its free end against acrosspiece, m, at the lower end of the stationary arm b, so as to openthe jaw K when the cam J is released. The auxiliary jaw K bears againstthe movable clamping-jaw D by means of an interposed spring, n, so thatboth jaws K and D are opened by the spring M when the cam J is released.

Upon tightening the cam J, which is effected by turning the handle Jlupwardly, the lower ends of the arms I. and K are simultaneously swungoutwardly, thereby swinging the jaws D and K toward the stationary jawB. After the clamping-j aw D has been closed against the saw O (placedbetween the jaws B and D) by the cam J, the auxiliary jaw K is stillfurther tightened by the raised cam l, thereby pressing the jaw Kagainst the saw below the clamping jaws B and D. This causes the saw tobe spru ng and to be tightly held against the clampingjaws B and D,whereby the saw is prevented from vibrating during the operation offiling. By holding the saw rigidly in the vise in this :manner thedisagreeable noise usually attending the operation of sharpening asaw isavoided, the labor of filing is lessened, and the wear of the filesreduced.

In order to insure a close fit of the auxiliary jaw against the saw saidjaw may be provided with a rubber cushion, p, seated in a recess formedin the face of the jaw.

I claim as my inventionl. The combination, with the support A, providedwith a spherical socket, G, of a vise provided with a spherical knuckle,F, seated in said socket, a screw-bolt, E, connecting the krickle of thevise with the socket G, and a screw-nut, H, applied to the bolt E,substantially as set forth.

2. The combination, with the support A, provided with a sphericalsocket, G, of a vise provided with a separate spherical washer, F, whichis attached to the vise and seated in the socket G, a screwdoolt, E, andnut H, substantially as set forth. y

3. The combination, with the clamping-jaws B and D, of an auxiliary jaw,K, which bears against the clamped'article andA springs or detleets thesame, substantially as set forth.

4. The combination, with the stationary clamping-jaw B, of the pivotedclamping-jaw D, and a pivoted auxiliary jaw, K, adapted to bear againstthe clamped article below the jaws vB and D, substantially as set forth.

5. The combination, with the stationary clamping-jaw B, provided with adepending arm, b, having ascending arms c, ofthe clamping-jaw D and theauxiliary jaw K, both pivoted to the arms c, substantially as set forth.

6. The combination, with the stationary clamping-jaw B, provided with adepending arm, b, of the pivoted clamping-jaw D, provided with arms I,the pivoted auxiliary jaw K, provided with an arm, k and the cam J,which closes the jaw D,and which is provided with araised portion, Z,whereby the auxiliary jaw K is closed, substantially as set forth.

7. The combination, with the stationary clamping-jaw' B, provided with adepending arm, b, of the pivoted clamping-jaw D, provided with arrns I,the pivoted auxiliary jaw K, provided with an arm, k, the cam-lever J Jspring M, attached to the jaw K, and a spring, n, interposed between thejaws D and K, substantially as set forth.

Witness my hand this 9th day of January, 1886.
